I showed you just the profile, I also have the data on how many kJ, too. By stage and overall.

What I like about a power meter is the real time information. You convert your 20 min power into other values. You learn what you can hold for x- minutes, so on a long climb, you can pace yourself. Same thing when biking in the wind.

Real time info makes for better intervals too. Here is a nice article on that.

Hmmm... so real-time info would be nice so you are aware of your current pace.

The article makes good sense, especially on a stationary bike, but I can't really visualize it working on the trails with varying degrees of climbs, obstacles and so on. Still it might just work and teach me how to pace myself..

To be honest, I'm not certain how effective a power meter would be on singletrack. I see it as more of a training tool. In a race setting, I think it is only really used for time trials and long climbs. In both cases, it is more of a rev-limiter. If you were doing a long mountain bike race (e.g., Leadville) it could be essential to make sure you paced yourself properly.

In a race, I also see no benefit of real time power metering.
It would be for training, and in particular for the aftermath of training and racing.
.....and just for fun ;)

I remember LeMond fooling with power meters back in the late 80s and swore by thier training benefits. From wiki:

Power meters provide instant feedback to the rider about their performance and measure their actual output; heart rate monitors measure the physiological effect of effort and therefore ramp up more slowly. Thus, an athlete performing "interval" training while using a power meter can instantly see that they are producing 300 watts, for example, instead of waiting for their heart rate to climb to a certain point. In addition, power meters measure the force that moves the bike forward multiplied by the velocity, which is the desired goal. This has two significant advantages over heart rate monitors: 1) An athlete's heart rate may remain constant over the training period, yet their power output is declining, which they cannot detect with a heart rate monitor; 2) While an athlete who is not rested or not feeling entirely well may train at their normal heart rate, they are unlikely to be producing their normal power—a heart rate monitor will not reveal this, but a power meter will. Further, power meters enable riders to experiment with cadence and evaluate its effect relative to speed and heart rate.
Power meters further encourage cyclists to contemplate all aspects of the sport in terms of power because power output is an essential, quantitative link between physiological fitness and speed achievable under certain conditions. A cyclist's VO2 max (a proxy for fitness) can be closely related to power output using principles of biochemistry, while power output can serve as a parameter to power-speed models founded in Newton's laws of motion, thus accurately estimating speed.[1] The joint application of power meters and power models has led to increasingly more scientific analyses of riding environments and physical properties of the cyclist, in particular aerodynamic drag.[2]

Nope. Maybe next year.
